PROBLEM TO BE SOLVED: To improve interest in a game in the case where a common performance appears again when the lapse of a period from the end of the last common performance is short, even after the lapse of a predetermined period from a first common performance.SOLUTION: After the execution of a probability variation suggestive performance (common performance) is finished, on the basis of a determination to resume the probability variation suggestive performance by lottery processing within a predetermined period from start of a probability variation latent mode, the execution of a probability variation suggestive performance of a type in which an expectation on a probability variable state is not reduced in comparison with the probability variation suggestive performance in the start of the probability variation latent mode is started. Even after the lapse of the predetermined period from the start of the probability variation latent mode, on the basis of sudden generation of a probability variation big win or small win within a specific period from the end of the execution of the last probability variation suggestive performance, execution of a probability variation suggestive performance of a type in which the expectation on the probability variable state is not reduced in comparison with the probability variation suggestive performance in the start of the probability variation latent mode is started. |
